Abstract

A supply system with a plurality of consumers, which can be supplied with a minimum volumetric flow by the supply system to ensure their operational function, wherein the supply system exhibits a network of lines with a plurality of lines, which are each hooked up to the consumers, and a pump connected to the lines for generating a volumetric flow of supply fluid in the lines, wherein the supply system incorporates a network of lines in which consumers are fluidically connected in parallel in relation to the pump arrangement, and wherein each consumer has allocated to it at least one flow control valve functionally placed upstream from the respective consumer in the cooling circulation as viewed from the position of the pump in the direction of flow.

First claim

The invention claimed is:

1. A supply system with a plurality of consumers, which can be supplied with a minimum volumetric flow of a fluid by the supply system to ensure operational function thereof, the supply system comprising:
a network of lines with a plurality of lines, which are each connected to the consumers;
a pump connected to the lines for generating a volumetric flow of the fluid in the lines, wherein at least two of the consumers are fluidically connected in parallel in relation to the pump arrangement: and
one or more throttle valves allocated to each of the two consumers;
wherein the one or more throttle valves are functionally placed upstream from a respective one of the two consumers in a cooling circulation, relative to a position of the pump in a direction of flow;
wherein the one or more throttle valves are self-regulating and configured to maximally limit a volumetric flow by generating a disproportional rise in pressure loss when a rated volumetric flow threshold in a respective one of the plurality of lines is exceeded, the disproportional rise in pressure loss being relative to a rate of increase in pressure loss below the rated volumetric flow threshold: and
wherein the volumetric flow processed by each consumer deviates at most by 20% from the rated volumetric flow threshold.

2. The supply system according to claim 1 , wherein a throttle valve is integrated at least in regions of the line network in each consumer.

3. The supply system according to claim 1 , wherein the supply system is a cooling system of an aircraft, and a cooling medium is used as the fluid.

4. The supply system according to claim 1 , wherein the supply system is an air conditioning system of an aircraft, and air is used as the fluid.

5. The supply system according to 1, wherein the supply system is a hydraulic system of a vehicle.

6. The supply system according to claim 1 , wherein the fluid is an incompressible medium.

7. The supply system according to claim 1 , wherein diameters of the plurality of lines of the cooling circulation are constant within a maximum deviation of 10%.

8. The supply system according to claim 1 , wherein the supply system is a cooling system for cooling storage containers that are stowed in stowage locations within an aircraft fuselage, the cooling system comprising at least one central cooling plant, at least one heat exchanger as a consumer arranged external to the storage containers at each of the stowage locations, a cooling medium, and a cooling medium distribution conduit system connecting the central cooling plant with the at least one heat exchanger, wherein the conduit system includes a supply conduit and a return conduit, which are each connected with the cooling plant, and connector conduits connecting the at least one heat exchanger with the supply and return conduits, and wherein, in each connector conduit, at least one throttle valve is installed, which is functionally placed upstream from a respective consumer in a respective connector conduit as viewed from the position of the pump in the direction of flow.

9. The supply system of claim 8 , comprising only one cooling plant.

10. The supply system of claim 8 , wherein the supply and return conduits are arranged below a cabin floor and extend over substantially an entire length of a cabin.

11. The supply system of claim 8 , comprising:
respective quick connectors provided on respective ones of the connector conduits and adapted to couple the respective connector conduit to one of the return and supply conduits at one of a plurality of coupling locations along the return conduit and the supply conduit, and
comprising connector adapters provided at the plurality of coupling locations along the return conduit and the supply conduit,
wherein the quick connectors are adapted to couple the connector conduits to the connector adapters.

12. The supply system of claim 8 , wherein the cooling medium is a liquid coolant, and the conduits of the cooling medium distribution conduit system are liquid coolant conduits.

13. The supply system of claim 8 , wherein the cooling medium is a vaporizable refrigerant, the supply conduit is a liquid refrigerant supply conduit, the return conduit is a vapor refrigerant return conduit, and the heat exchanger is an evaporator.

14. The supply system of claim 8 , wherein the cooling medium distribution conduit system further comprises a pump adapted to convey the cooling medium through the cooling medium distribution conduit system.

15. The supply system of claim 8 , wherein the cooling plant comprises a compression cooling plant.

16. The supply system of claim 8 , wherein the cooling plant comprises a fuselage skin heat exchanger arranged on the aircraft fuselage.

17. The supply system of claim 8 , wherein the cooling plant comprises a liquid/air heat exchanger adapted to be cooled by a primary cooling air flow, wherein the aircraft further includes air conditioning packs, and wherein the primary cooling air flow is a cooled air flow provided by the air conditioning packs.

18. The supply system of claim 8 , wherein the cooling plant comprises an adsorption cooling apparatus.

19. The supply system of claim 12 , wherein the liquid coolant is a water/glycol mixture.
